One company recently conducted a survey in which 420 women and 420 men were asked "Are you satisfied with the work of the Minister of Health?". Of these, 155 men and 118 women said they were satisfied with the minister's work. Assume that the experimental design was correct. Questions 1 and 2 cover this survey. 1. Find the upper limit of 95% confidence interval for the difference in the proportion of men and women who are happy with the work of the Minister (let men be group 1). 1. 0.03. 2. 0.09. 3. 0.15. 4. It is not possible to apply a normal approach and therefore we can not calculate the confidence interval. 2. What is the rejection area if it is to be examined whether the proportion of men and women who are satisfied with the job of Prime Minister is different (use a = 0.05)? 1. RejectHO efz <-1.96 or> 1.96. 2. Reject HO if z> 1.64. 3. RejectHO efz> -1.96 or <1.96. 4. Insufficient information provided to answer this.

Question
One company recently conducted a survey in which 420 women and 420 men were
asked "Are you satisfied with the work of the Minister of Health?". Of these, 155 men
and 118 women said they were satisfied with the minister's work. Assume that the
experimental design was correct.
Questions 1 and 2 cover this survey.
1. Find the upper limit of 95% confidence interval for the difference in the proportion of
men and women who are happy with the work of the Minister (let men be group 1).
1. 0.03.
2. 0.09.
3. 0.15.
4. It is not possible to apply a normal approach and therefore we can not
calculate the confidence interval.
2. What is the rejection area if it is to be examined whether the proportion of men and
women who are satisfied with the job of Prime Minister is different (use a = 0.05)?
1. RejectHO efz <-1.96 or> 1.96.
2. Reject HO if z> 1.64.
3. RejectHO efz> -1.96 or <1.96.
4. Insufficient information provided to answer this.
